A mid-1980s arcade game where you pilot a ship through an asteroid field mining for bombs to use against a super-demonic space robot called Sinistar, which is being built by swarming drones and defended by fast-firing tanks. Once Sinistar's construction is completed, he starts threatening and taunting you ("Run, Coward!") and makes a beeline to your sorry hide. The stress level involved gets ridiculously high. It is/was quite possibly the toughest arcade game in human history.
